How do you solve #36- 9\div [ ( 0.24\times 5) + ( 0.66\times 5) ]#?

Answer 1

Noah Archer

Apply the BIDMAS rule and first work out the brackets.

(The BIDMAS rule being: B rackets, I ndicies, D ivision,
M ultiplication, A ddition, S ubtraction)

#(0.24xx5)=1.2# #(0.66xx5)=3.3#

It then becomes:

#36-9-:[1.2+3.3]# #36-9-:4.5#

Apply the BIDMAS rule and do the division next and then the subtraction last.

#9-:4.5=2# #36-2=34#
